摘要:
Cooling of an enclosed space is effected by means of a cooling system comprising a plurality of cooling units forming ducts having an internal surface on which a layer of liquid is developed, e.g. by means of a wicking material, and through which air from the enclosed space is passed in contact with the liquid layer whereby the liquid is exposed to and evaporates into the air-flow with consequent cooling of the duct wall on which the liquid layer is developed.

L'invention porte sur une installation (1) de régulation thermique multizone intégrant une centrale d'air à dessiccation (2), un générateur thermique (3), plusieurs systèmes de mesure (C1, ...C6 1 , C6 2 ) de la température et de l'humidité relative, en particulier dans les zones, des systèmes de régulation (41, 42, 43, 44) de certains des composants de centrale d'air à dessiccation (batteries chauffantes (24R, 24S), humidificateurs (25R, 25S), roue dessiccante (21), ventilateurs (23R, 23S) et échangeur thermique (22)), un système aéraulique (5 1 , 5 2 ) de réglage du débit d'air dans chacune des zones, et une unité de pilotage (7) qui pilote les composants de la centrale d'air à dessiccation (2) pour qu'elle délivre de l'air à une température et une humidité relative dites de soufflage prédéterminées, et qui pilote les systèmes aérauliques pour que les systèmes aérauliques soufflent chacun de l'air à ladite température de soufflage, à ladite humidité relative de soufflage et à un débit dit de soufflage propre à chacune des zones.
摘要:
A fresh air heating unit has a casing (2) containing a stale air flow path (25) and a fresh air flow path (14). Combusted gas products from a gas burner (29) are mixed with the fresh air to heat it to a desired temperature before it is discharged into an enclosure. The two paths extend through a heat exchanger (15) and the rate of flow of stale air driven by a fan (26) through the casing is substantially equal to the rate of flow of fresh air driven through the casing by a second fan (21). As the rate of flow of fresh air from the casing into an enclosure is substantially matched by the rate of flow of stale air from the enclosure, and heat is transferred between the two air flows by the heat exchanger (15), a total replacement of air in the enclosure at a relatively high rate can be sustained in an economically viable manner. The level of noxious combustion products in the enclosure and produced by the gas burner (29) can thus be kept beneath that regarded as harmful by health authorities.

Ein Plattenwärmetauscher zur Beaufschlagung eines Zuluftstroms (3) mit Kühlenergie, die im Plattenwärmetauscher einem vor Durchströmen des Plattenwärmetauschers befeuchteten Kühlluftstrom (5) entziehbar und auf den Zuluftstrom (3) übertragbar ist, hat Wärmetauscherplatten (1), die an ihrer einen Seite (2) vom Zuluft- (3) und an ihrer anderen Seite (4) vom Kühlluftstrom (5) kontaktierbar sind und deren vom Kühlluftstrom (5) kontaktierte Seiten (4) mit einer hydrophilen Lackbeschichtung (6) versehen sind, die mit Feuchtigkeit aus dem Kühlluftstrom (5) benetzbar ist. Um Temperaturschwankungen auf der vom Zuluftstrom (3) kontaktierten Seite (2) der Wärmetauscherplatten (1) infolge zeitlicher Taktung einer den Kühlluftstrom (5) stromauf des Plattenwärmetauschers befeuchtenden Bedüsung zu vermeiden, wird vorgeschlagen, dass die hydrophile Lackbeschichtung (6) auf der vom Kühlluftstrom (5) kontaktierten Seite (4) der Wärmetauscherplatte (1) so ausgebildet ist, dass in ihr Feuchtigkeit aus dem Kühlluftstrom (5) speicherbar ist.
摘要:
A multi-stage hybrid evaporative cooling system is described as having a direct evaporative cooling subsystem and an indirect evaporative cooling subsystem having one of a horizontal and a vertical set of heat exchanger channels. The multi stage hybrid evaporative cooling system with a horizontal set of heat exchanger channels has a portion of the horizontal heat exchanger channels partially extended into a next stage of the multi-stage system. The multi-stage hybrid evaporative cooling system with the vertical set of heat exchanger channels includes a first set of vertical set of heat exchanger channels spanning a substantial vertical height of the stage of the hybrid evaporative cooling system, and a second set spanning approximately half the height of the stage. The multi-stage hybrid evaporative cooling system further includes a refrigeration system for lowering the temperature of the indirect evaporative cooling subsystem air without affecting its pressure flow.
摘要:
Method for cooling air, characterized in that it consists in the cooling of an air stream (11) on the one hand by sending it through a primary canalization (3) of a heat exchanger (2), and by vaporizing fluid (6), in particular water, in a secondary canalization (4) of this heat exchanger (2) on the other hand by means of an auxiliary air stream (12) which is tapped off the air stream (11) leaving the primary canalization (3).
